To (11140710114 '1' t may concern:

Be it known that I, DANIEL R. BLAKES- LEE. a citizen of the UnitedStates of Amen ica, residing at Vanburen, in the county of (u-ant andState of Indiana, have invented 322,096 filed June 16,1906, and hasrelation more particularly to the wheel employed therei The inventionhas for its object to provide novel means whereby the rim of the wheelis secured to the hub in such a manner that the rim in its rotation willexert on the hubboth a msh and a pull. It is also an object of thisinvention to provide a device which will prove sim 10 in construction,eflicient in practice an economical .to manufacture.

With the above and other objects in view, the invention .consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully set forth and claimed.

In describing the invention in. detail reference .will be had to the'accompanying drawings forming part of this specification in which likecharacters denote corresponding parts in the several views and in whichFigure l, is a fragmentary view illustrating the wheel in top plan. Fig.2, is a central section. Fig. 3, is a detail view showing the meanswhereby the spokes are secured to the hub.

Mounted on a suitably )ositioned shaft 1, is a hub 2, which may be ofany ordinary construction. but is shown in the drawings as in theco-pending application of which this is a division.

Formed with the hub isthe eccentric 3. The eccentric is operated bymeans of a belt 4, passing aroum the rim 5, which is colinected to thehub by the spokes 6 and 7. 4

This rim may be of any required circumference'and is formed of a seriesof overlapping bentstrips of wood, preferably of three thicknesses. Thelower ed 6 of therimisprovided with an outstanding ange a which [S forthe purpose of preventing the belt passing therearound from slippingoff. The rim provided with a series of apertures through which projectthe headed spoke sections 8, having their free portions threaded theouter ends of the openings of the rim fbeing countersunk so that thetops of the blinds of the spoke sections will be flush with theperiphery of the rim when in applied positiom Secured to the spokesections are turn buck les 9, which in turn engage the threaded ends ofthe spokes 6', and 7. The spokes 6, are secured to the eccentric 3,tangentially of the periphery thereof. It is to be noted that the spokesbefore they are connected to the'eccentric cross each other. By thisarrangement, as is thought obvious, a push and pull will be exerted onthe eccentric by the-rotation of the wheel. The spokes 6, extendentirely across the interior of the rim and are provided withapproximately V-shaped oil'- sets 10, which pass through the o enings11, of theeccentric and are engaged y the keys 12 which hold said spokesin engagement with the eccentric.

The spokes 7, are secured to the upper end I .of the hub 2, as isplainly shown in t e (.llfiV.

The eccentric is provided with a flange 13, arranged adjacent the edgethereof. Embracing this flange 13, and restim on the eccentric is a starwheel 14, which has depending from its points, the hooks 15. To thesehooks 15, are fastened the ends of the" pull rods 16, which in thepresent instance are in tended to operate oil well pumps. It is to bestated that this structure, however, forms no part of the presentinvention.

I also provide the hub 2, with a duct 17, through which oil may be fedto the bearings of the working arts of the device.

Having thus escribed my invention, what I claim as new and wish tosecure by Letters Patent, is-

1. In combination a wheel comprising a hub having a continuousflange, arim, and spokes connecting said flange and 'rini, said spokesex'tendingentirely across the wheel tangentiall of the flange, and means carriedby the spokes for exerting a pressure on the inner surface'of theflange. 2.. In combination, a wheel comprising a hub having a continuousflange, said flange being perforated, a rim, spokes connecting saidflange and rim, said spokes extending entirelya'cross the wheeltangentially of the flange and having ofl'sets protruding through theperforations of the flange, and means engaging the offsets acting inconjunction with f through theofl'sets bearing against the inner theflange for exerting a pressure on the ini surface of the flange toexertrcssuro thereon. ner surface of the flange. 1 In testimony whereof I aix my signature 3.
